RS resonance in di-final state production at the LHC to NLO+PS accuracy

We study the di-final state processes ($\ell^+ \ell^-$, $\gamma \gamma$, $ZZ$, $W^+ W^-$) to NLO+PS accuracy, as a result of both the SM and RS Kaluza-Klein graviton excitations. Decay of the electroweak gauge boson final states to different leptonic states are included at the showering stage. A selection of the results has been presented with PDF and scale uncertainties for various distributions. Using the di-lepton and di-photon final states, we present the search sensitivity, for the $14$ TeV LHC at $50$ fb$^{-1}$ luminosity.Comment: 20 pages, 14 figure

Assessment of Water Quality Around Mine Sites

One of the major impacts of mining processes is the contamination of water bodies through mine water drainage, leakage of water exposed to minerals, water from soil heaps, acid mine drainage and mine water rebound. Water is the most important element of eco-system and it is thus imperative to determine and mitigate the effects of mining operation on the same. Also, contaminated water has adverse physiological effects on human being and other animals. For this, it is important to identify the critical parameters in the water sample which is the scope of the study. Sampling, Water quality parameters and their tests: Samples were collected from different mines including both coal and metal mines spread over northern and western Odisha such as samples from Ib Valley coal mines of MCL, discharge of iron mines from Chhattisgarh and Koira region and were analysed through a series of experiments following standard procedure. The concentration of various physical, chemical, metallic and organic parameters were found which included determination of turbidity, conductivity, solids, iron, chromium content, pH, hardness, ammonia, nitrate, sulphate, phenol, fluoride, phosphate and organic parameters of importance such as Dissolved oxygen, Bio-chemical Oxygen Demand and Chemical Oxygen Demand. Results and Discussions: The results indicated that discharge of iron mine, Chhattisgarh, exceeds the contamination limits for physical and metal parameters but is within limits for others. Samples from the coal mining areas are having elevated concentrations of physical, chemical and organic parameters, such as solid content, turbidity and dissolved oxygen. Samples from metal mining region of Koira showed higher iron content and other nutrients. The results were quantified to determine the degree of contamination. The values of degree of contamination (Cd) are given in the table-1. The Cd values indicate that the water samples from coal mines, iron mines of Chhattisgarh, Barsuan and Bandhal from Koira region are heavily polluted.

Designing of Zinc Oxide Thin Film Electrode based Continuous Impedance Monitoring System

The study describes the analysis of d-glucose solutionby a Zinc Oxide (ZnO) thin film biosensor. The ZnO thin film sensor was developed by the RF sputtering method over a glass substrate. Two adjacent electrodes were used to measure the impedances of the various concentrations of d-glucose. A in-house developed contiuous monitoring system was also used to study the impedances of the same and it was also tested for its continuous monitoring capability of the impedances of the d-glucose concentrations

Stratification relieves constraints from steric hindrance in the generation of compact acto-myosin asters at the membrane cortex

Recent in-vivo studies have revealed that several membrane proteins are driven to form nanoclusters by active contractile flows arising from F-actin and myosin at the cortex. The mechanism of clustering was shown to be arising from the dynamic patterning of transient contractile platforms (asters) generated by actin and myosin. Myosin-II, which assemble as minifilaments consisting of tens of myosin heads, are rather bulky structures and hence a concern could be that steric considerations might obstruct the emergence of nanoclustering. Here, using coarse-grained, agent-based simulations that respect the size of constituents, we find that in the presence of steric hindrance, the patterns exhibited by actomyosin in two dimensions, do not resemble the steady state patterns observed in our in-vitro reconstitution of actomyosin on a supported bilayer. We then perform simulations in a thin rectangular slab, allowing the separation of a layer of actin filaments from those of myosin-II minifilaments. This recapitulates the observed features of in-vitro patterning. Using super resolution microscopy, we find direct evidence for stratification in our in-vitro system. Our study suggests the possibility that molecular stratification may be an important organising feature of the cortical cytoskeleton in-vivo

Potential Anticancer Drugs Targeting Immune Pathways

Studies on the tumor microenvironment reveal that infiltration or induction of tumor-associated immune regulatory populations at the local tumor site is strongly associated with severe immunosuppression as well as worse prognosis of patients. Despite major advances in cancer immunotherapy, most of the therapeutic agents often fail to break negative immunosuppressive network to trigger anticancer immunity, leading to tumor progression and metastasis. Therefore, emergence of potent immunostimulatory agents is of great clinical importance. Emerging evidence suggests that metal chelates of Schiff bases hold the promise to overcome tumor-associated immunosuppression by inhibiting or subverting suppressive immune population toward pro-immunogenic type and thus can be used clinically for immunotherapy of different types of cancers

Strong, lightweight, and recoverable three-dimensional ceramic nanolattices

Ceramics have some of the highest strength- and stiffness-to-weight ratios of any material but are suboptimal for use as structural materials because of their brittleness and sensitivity to flaws. We demonstrate the creation of structural metamaterials composed of nanoscale ceramics that are simultaneously ultralight, strong, and energy-absorbing and can recover their original shape after compressions in excess of 50% strain. Hollow-tube alumina nanolattices were fabricated using two-photon lithography, atomic layer deposition, and oxygen plasma etching. Structures were made with wall thicknesses of 5 to 60 nanometers and densities of 6.3 to 258 kilograms per cubic meter. Compression experiments revealed that optimizing the wall thickness-to-radius ratio of the tubes can suppress brittle fracture in the constituent solid in favor of elastic shell buckling, resulting in ductile-like deformation and recoverability

Introduction d'aléas dans le processus de projection d'applications sur CGRA

National audienceLes architectures reconfigurables à gros grains offrent un compromis flexibilité-performance intéressant à travers les nombreuses unités de calculs élémentaires qu'elles proposent. Cependant, projeter automatiquement une application sur une architecture reconfigurable à gros grain est un processus complexe qui nécessite d'explorer un vaste espace de solutions. Cet article propose d'étudier l'apport d'aléas dans le processus de projection. L'introduction d'aléas est effectué en particulier dans les étapes d'ordonnancement et d'assignation. Différentes stratégies permettant de garantir un nombre minimum et maximum de solutions sont présentées. Les résultats montrent que notre méthode, couplée à une approche de transformation du graphe d'application, explore mieux l'espace de solutions et permet de trouver la latence la plus courte
